Abstract
Provided is a dual-neighborhood wear angle automatic detection method, including constructing a proximal neighborhood and establishing grayscale differences between a pixel in a center area and pixels having first directions in the proximal neighborhood; calculating, based on the grayscale differences, deviation degrees of all pixels in the center area in the first directions; calculating a similar direction value based on the deviation degrees; constructing a distal neighborhood and focus pixels having second directions in the distal neighborhood; calculating grayscale differences between the pixel and the focus pixels; calculating deviation degrees of all pixels in the center area, in the second directions based on the grayscale differences between the pixel and the focus pixels; calculating a direction value of a wear angle based on the deviation degrees in the second directions; and calculating the wear angle based on the direction value of the wear angle.
